Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
A collapse of western 21st century civilization to a hunter-gatherer system means massive die-off of humans. There's never been enough natural food to support our population booms.

A hunter-gatherer-based system presumes a healthy ecosystem that will support the production of edible animals and plants. With accelerating climate change, all bets on the future are off.

We've reached a place where we've poisoned the entire world and entire species are going extinct through our pollution and exploitation.

Even if we humans vanish tomorrow, the CO2 in the atmosphere, the petroleum spills, plastic gyres in the oceans, and so forth will remain. The CO2 will take centuries to mitigate naturally and the plastic doesn't decompose. New life would need to evolve to handle the mess we leave behind.
